The hyaluronidases (EC 3.2.1.35) are a family of enzymes that degrade hyaluronic acid. In humans there are six associated genes including HYAL1 HYAL2 HYAL3 and PH-20/SPAM1.

Melittin is the principal active component of apitoxin (bee venom) and is a powerful stimulator of phospholipase A2. Melittin is a peptide consisting of 26 amino acids with the sequence […]

Mitogen-activated protein kinases also known as MAP kinases are serine/threonine/tyrosine-specific protein kinases belonging to the CMGC (CDK/MAPK/GSK3/CLK) kinase group. The closest relatives of MAPKs are the cyclin-dependent kinases (CDKs). MAPKs […]

Photosystem I (PS I) (or plastocyanin: ferredoxin oxidoreductase) is the second photosystem in the photosynthetic light reactions of algae plants and some bacteria. Photosystem I is so named because it […]

Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants algae and cyanobacteria. The […]

Connexins or gap junction proteins are a family of structurally related transmembrane proteins that assemble to form vertebrate gap junctions (an entirely different family of proteins the innexins form gap […]

Malate dehydrogenase (EC 1.1.1.37) (MDH) is an enzyme that reversibly catalyzes the oxidation of malate to oxaloacetate using the reduction of NAD+ to NADH. This reaction is part of many […]

Interleukin 2 (IL-2) is an interleukin a type of cytokine signaling molecule in the immune system. It is a protein that regulates the activities of white blood cells (leukocytes often […]

Glycogen synthase kinase 3 (GSK-3) is a serine/threonine protein kinase that mediates the addition of phosphate molecules onto serine and threonine amino acid residues. First discovered in 1980 as a […]

MyoD is a protein with a key role in regulating muscle differentiation. MyoD belongs to a family of proteins known as myogenic regulatory factors (MRFs). These bHLH (basic helix loop […]
